FYI ... I found out today that accidentally leaving one of the hoses on the intake near the air filter disconnected after changing the air filter will throw the exact code for this bank1 sensor2 O2 sensor failure my torque app said the light was on for 'o2 sensor slow to respond' if you have this code for bank1 sensor 2, first check all of the hoses that attach to the intake before digging into this O2 sensor repair - especially if you've recently had the air filter out if writing this helps at least one person it's worth it
P1037 is Bank 1 Sensor 2 which is the O2 Sensor AFTER the catalytic. 1st check for exhaust leaks, fix any and clear the code, if it returns, check the wires for fraying or cuts and check the connection. The code is stating there is low voltage detected. Lastly replace the O2 sensor behind the catalytic, my preference is Denso any day of the week. Oh and the connector for Sensor 2 with the 4 cylinder is located underneath the front passenger seat..
This sensor is the "downstream" O2 sensor on the 05 Hybrid Accord. The upstream being the A/F sensor as the warm up three way catalytic converter is attached to the cylinder head. I note this because the upstream is more expensive so I hope I could save somebody some money.
But this video is for the 03-06 non-hybrid Accord. (The downstream in the regular Accord is under the passenger seat, well after the engine's exhaust flex section.) This video shows replacement of the upstream sensor on a non-hybrid Accord.
I have code po420 and po139 o2 circuit slow response (bank 1, sensor 2) will replacing the sensor take both codes off? My check engine light has been off for like a month or so but it comes on again here and there for like 2-3 days and goes away . I need help I don’t want to replace the cat.
coupla notes - the photography on this video is good. where you bent the heat shield, ,thats a small retaining loop for the sensor wire. if you buy the right O2 removal socket you can attach it to a 3/8 ratchet. I really dont think you want anti-seize on that sensor. they are very susceptible to certain chemicals.
I have the same exact code. I got the sensor attached to the cat. Hopefully that knocks off the P0420 code. If not. I'll just buy the one for the front.
@@jeremiahcuthbert1300 to be honest man. I would highly recommend to fix it right away. It's not worth your car getting totally fucked. It's also an easy fix.
So I’m getting a code p420 the old Cadillac converter was stolen and he replaced it for 500 but don’t changed one of the sensors the one under the drivers side and wheel witch my mechanic said is the upstream one and I bought a denso one for 130$
Thanks, curious how did you decide if it's Upstream or downstream? I have a 2007 Accord and getting P0420 on Bank 1, means downstream sensor? Thank you :)
@@jesseboy310Did you figured it out ? 😙 It's been a year since you got the same code p420. Please share your experience in solving the same issued after changing the Catalytic and both O2 sensor that got stolen during rainy day. 😙
You bought cheap sensors. They are faulty. It happened to me several times when I didnt buy name brand. (No clue what brand you bought). If you did buy name brand check your wiring. NTK or oem are great brands
I cant find my sensor plug, i cant find where the wire is coming from. It seems it was cut off, Pls do a video to show me where to find the wire so i can connect it
Hello may some 1 please tell me how to fixs my honda accord it's a 2004 my car 02 sensor need to be fixs and when I drive like 40 mph it shakes a little my transmission fluid is full the man told me that's what I have 2 get fixs so it will drive good
@@robertarrington1440 how are the spark plugs are coils. When my accord went into limp mode it was the drive by wire module towards the back of the firewall. But that's the 2006-2007 variant. Do you have a CEL which code you've read?
Does this fix eliminate the car stalling and dying when idling. That's the problem I'm having rite now. My code came up as a p2195. Car accelerates when driving but wants to die when coming to a stop or just idling. Any help would b great. Thanks.
I recently changed the spark plugs and am waiting on a new set of ignition coils I ordered online. I was getting the codes of 2 cylinders misfiring. Bout 3 days ago is when my car started stalling and dying out. I read the code again and p2195 came up. Stuck lean bank 1 sensor 1.
jerry correa Same thing happened to me 1st a code for the oxygen sensor and then a code came up for a miss fire once I replace the oxygen sensor and four coil packs everything is good to go
Fortunately I don't remember because the video was made so long ago if I was you I would replace both of them because after replacing one Soon after the other one will fail
@@thebestever333 yes it is and he’s right I replaced the rear o2 on the cat and 2 months later here I am replacing this o2. And make sure you go with denso
So am I. I can only get one hand on the cable connector. I've stuck a small screwdriver on top of the clip and I've tried pressing the tab down but I can not get the connector off. Sprayed WD40 on it for the night and will try again tomorrow. On top of that the sensor will not budge. Gonna put a torch on it tomorrow. What a pita.
Hi, my 2005 accord has two error codes popped up P0139 and P0141). Which code indicates the upstream sensor??? Thank you. I have 2 codes show up. Does that mean I have to replace both???
@@oOohdaddy I only read about it. I bought a Denso sensor # 234-4797 for my 2004 Accord Lx and after 1.5 years, no problem. So i would recommend that. I did not want to take the risk of having to do the job twice.
@@oOohdaddy It's the one under the passenger seat of the car, the one that you have to unscrew the passenger front seat to install (use breaker bar, those security nuts are tight) and there's a rubber grommet on the sensor cable, that installs in the car floor hole. I found that the new cable was missing the three small rubber holder clips, so i had to re-use the ones mounted on the oem cable. But to do that i had to cut them open which isn't perfect, but you'll find the sensor cable won't hang under the car anyway even without using them. That was a minor let down. Maybe all the replacement parts are this way. Well, it works and i didn't pay for a Honda part which would be more.
@@FLORIDALIFECLIPS thanks, its gonna be at least $250. Question.. I got a 04 Honda accord 4cyl, at 161k miles. In your opinion, How much longer i got on this car? Also how do i make sure it stays reliable? Thank you in advance.
@@JolinHard had a 2000 accord with 285k and my 04 now has 159k even if the previous owner neglected the car they still live long they’re pretty much bullet proof. And easy to work on no point in paying anyone to work on this car it’s super easy.

What exactly is that sensor connected too? because it can’t be a converter because when you look them up they only sell one for sale.

Do both.
Yes always do in pairs, if one goes bad the other probably isnt far behind it.
Hey bro same year accord same code, what was the issue?
I have an 05 with the same code did you figure it out?

What code were you throwing?
Did you have to reset the fault codes when you reinstalled the new part?
No
Stick with Denso, cant beat OEM.
I replaced both of those sensors on my 2006 CR-V and I still get the P1157 H02S(A/F SENSOR) S1 AFS LINE VOlTAGE HIGH
No clue try to go on some Honda forms site and ask them.

Aint this bank 2 sensor 2..bank1 sensor 2 i tho it was the rear?
It doesn't matter replace them both
Is that the V6 or 4 cylinder. One of them showed the upstream connector under the front driver seat.
My is a 4
Downstream sensor is under the passenger seat on a 4-cyl '03.
how has this worked sor far??? got the same issue
I get rid of the car along time ago word of advice do both of them

did u fix it? i"m having this problem ubering so now on monday i will not work with it like that.it's my only car to work

@@quancast1141 thanks bud
Does it have to be original sensor cause I replace one and the code came back on
Disconnect your battery fir a few min. or hook up a scanner and delete the code
@@FLORIDALIFECLIPS yeah I did same thing
I think you are supposed to remove the lower heat shield first.
Well this P O S was from up North and had lots of rust.
Federal or California ? What's the difference between California and federal?
I don't know if I'm using the wrong O2 sensor
Very informative. Thank you so much. ❤
I'm getting P0139 code is that down stream or upstream cant afford to do both.
Google it, it should be the downstream though. Go to RockAuto.com, it has some of the best prices and hands down beats any auto parts dealer on price.
WHERE DID YOU PLUG THE OTHER SIDE OF THE SENSOR?
I don't remember this video was made very long time ago I haven't had the car in years
My light still keeps coming g on for t hi is sensor any help why
Have you disconnected your battery Cleared it with a scanner
Man im having a problem unclipping my upstream sensor everything changed out downstream sensor wasnt any problems
Just be a little bit more specific what you're having problems with I'll trying to help you
So am I. I can only get one hand on the cable connector. I've stuck a small screwdriver on top of the clip and I've tried pressing the tab down but I can not get the connector off. Sprayed WD40 on it for the night and will try again tomorrow. On top of that the sensor will not budge. Gonna put a torch on it tomorrow. What a pita.
Denso over NTK? What y’all think?
Denso
Did you do the MAS Airflow sensor?
Yes
do you have to jack up your car to replace this sensor?
Is this P0154 Bank 2 sensor 1??
Replace both because the other one will follow after I replaced the other 1
Your video is what I'm looking for. My honda 2007 accord se is same as yours where the o2 sensor is located the same unlike other videos.
Underneath towards the front
You realize that there is more than one sensor right?? So maybe the other videos you saw were of the same car just the other sensor instead
I got a honda accord ex 2007 with code P0135 that up or down?
Replace both because the other one is not far behind
what fault code u get for this sensor?
Sorry don't remember
@@FLORIDALIFECLIPS ok thanks
you should use denso or ngk instead of bosch... bosch only used on european cars sir!
Nope, not only euro's. Gm, honda and toyota have been using some bosch for a while
@@CaffeineFreak13 nope not very successfully. Go ahead and throw some Bosch spark plugs in that Honda see how well it runs from there
Is this for bank 1 sensor 1 or 2?
Im 90% sure this is bank 1 sensor 1. Sensor 2 would further back

2
I have the same problem right now,can you tell me what the name of the sensor sir,I got a 2005 Honda Accord
I used a Bosch sensor
I mean what sensor is
Don’t use Bosch sensor or ntk oem only
It fits a 2006 ?
Double check the part number with your local parts store
